9.2 Fitting the fan assembly
To replace the PSU fan assembly proceed as follows:
•
Offer up the fan assembly ensuring that the lug fits into the slot in the right hand side of
the frame
•
Carefully move the fan assembly into position, ensuring that the PSU fan jack fits into the
PSU jack socket (SK 1)
•
Take care not to damage the panel ribbon cable
•
Tighten the captive screw to the left of the PSU fan – it need only be hand tight
•
If the unit was unpowered it may now be powered and tested
Replacing the PSU fan
It is recommended that PSU fan replacement should be performed as quickly as possible if
performed whilst the frame is powered, to prevent overheating.
Tip:
Close the front panel whilst the PSU fan assembly is removed when the frame is
powered, to allow the front panel fan to operate and provide cooling.
To replace the PSU fan proceed as follows:
•
If possible disconnect the power cord from the frame
•
Remove the PSU fan assembly as shown in the preceding section
•
Undo the three-way connector which is attached to three wires on the fan
•
Remove the finger guard and fan by unscrewing the four retaining screws
•
Replace the fan with a Crystal Vision supplied replacement part to ensure adequate
cooling and continued fire protection
•
Be sure to refit finger guards on the outer side of the mounting plate assembly
•
Plug in the three-way connector from the new fan
•
Replace the PSU fan assembly as shown in the preceding section
•
Reconnect the power supply cord
If the frame is powered, the PSU fan should now be operating and the PSU FAN LED should
be green.
